AGRICULTURAL IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 651,093, dated June 5, 1900. v

Application filed March 30,1898.

To all whom it may cancer/0.

Be itknown thatl, SAMUEL L. ALLEN, a citizen of the United States, and a resident of Moorestown, county of Burlington, State of New Jersey, have invented certain new and useful Improvements in Agricultural Implements, of which the following is afull, clear, and exact description, reference being had-to the accompanying drawings, forming part of this specification.

This invention relates to certain improvements in agricultural implements, and more particularly to doublerow riding-cultivators.

The main object of my invention is to generally improve, strengthen, and simplify the construction of machines of this character and also to produce a machine which can be arranged and adjusted for a great variety of work in various kinds of crops.

Another object of my invention is to provide for the adjustment of the cultivatorteeth and their supporting-frames both laterally and as regards the depth of penetration of the soil and to provide for the adjustment of the downward pressure exerted upon the teeth.

A further object of my invention is to provide means for limiting the downward movement of the teeth and their carrying-frame,

and thereby preventing too great a depth of penetration when a soft soil is reached.

A still further object of my invention is to provide for the lateral adjustment of the supporting-wheels and the teeth-carrying frames, so that the machine can be adapted for work on rows of different widths.

A still further object of my invention is to 1 provide an improved construction of pivotwheel and improved means for turning said wheels to guide the machine; also, to provide means for retaining the wheels at an angle to the draft of the machine when working on hillsides, so as to take up the lateral slipping, which is always occasioned on inclined surfaces.

A still further object of my invention is to provide a teeth-carrying frame surrounding the supporting-wheels, so that teeth can be located outside of said Wheels, and thereby greatly diminish the width of the wheel-supporting frame, which tends to cheapen and Serial No. 675,678. (No model.)

generally improve the value and appearance of machines of this character.

A still further object of my invention is to provide an improved clamping means for securing the teeth to the carrying-frames which is capable of both vertical and lateral adjustment; also, to provide an improved construction of shank for'the teeth.

WVith these main objects in view my invention consists in the construction, combination, and arrangement of parts, such as will be hereinafter particularly set forth and particularly pointed out in the claims made hereto.

Referring to the drawings, in which similar letters and numerals of reference are used to indicate like parts, Figure 1 is a side elevation of a machine constructed in accordance with my invention. Fig. 2 is a plan view of the same, the segmental rack and lifting mechanism being omitted. Fig. 3 is an end elevation of the same, the teeth-carrying frame being shown in section.

Fig. 19 is an enlarged detail section showing my improved clamp for securing the teethshanks to their carrying-frame. Fig. 20 is an enlarged perspective of the clamp-frame. Fig. 21 is an enlarged detail perspective of the followenblock of the clamp. Fig. 22 is a diagrammatic view.

In the drawings, A designates the supporting-wheels, which are mounted on axles a, said axles being bent at right angles into vertical pivot-bars a, which have a hearing at their upper ends in a clamp B, which is socured to the main supporting-frame C.

E designates the tongue-bars, which are secured by means of straps and bolts to the frame 0. 1n the forward part of the machine is a transverse frame-rod D, which is provided with a yoke-shaped central portion which extends upwardly and slightly rearwardly and is secured to the under sides of the tongue-bars E.

E designates brace-bars which connect the frame D with the cross-bar F, secured at the front of the machine to the tongue-bars E. Brace-rods E also connect the frame D at the beginning of its upwardlyextending yoke portion with the cross-bar F, and bracerods E connect the blocks at the lower ends of the pivot-bars with the said front crossbar F, said braces being all for the purpose of strengthening and giving sufficient rigidity to the frame of the machine.

Secured on the frame-rod D are the bars G G, which form the substantially diamondshape teeth-carrying frame. These bars are provided with hubs around the apertures in their forward ends and are adapted to slide on the frame-rods D and be rigidly secured thereon by means of set-screws g, so that the said teeth-carrying frames can be adjusted laterally to admit of working rows of different widths. A supplemental bar G is bolted to the bar G at its forward end and extends across to the bar G and extends parallel therewith until it reaches the beginning of its diamond-shaped portion, Where it extends outwardly and over to the point G of the bar G, and is secured thereto by means of bolts or rivets. This is for the purpose of strengthening and bracing the tooth-carrying frame and affording a connecting-point for the lifting-lever H. To the upper end of the liftinglever H is pivoted an auxiliary lever K, having its forward end bent downwardly, as shown in Fig. 1 and in dotted lines in Fig. 1]. of the drawings. The downwardly-projecting end of the lever K is provided on its inner side with a hub K, (see Fig. 13,) into which fits atrunnion K formed on a bracket K which is secured to the under side of one of the tongue-pieces E. (Shown most clearly in Fig. 11 of the drawings.)

Located on the top of each of the tonguepieces G is a segmental rack I, having pivoted thereto a hand-lever I, which carries a spring-pawl adapted to engage with the teeth of the said rack and be operated by means of the usual wire connections with the handle. The lower part of the lever I is in the form of a bell-crank lever I and is connected, by means of a link 1 with a lever I. This lever 1 is bent over at its rear end to form a bearing fora roller J ,said rollerbein g adapted to travel on a track J, formed on the rear face of the auxiliary lever K, the rear end of which is pivotally connected to the liftinglever II, as heretofore described. To the forward end of the lever I is secured a coiled spring L, the other end of which is, secured to an cyebolt L, bolted to the front cross bar of the machine-frame. The tension of this spring L can be adjusted by regulating the nut on the end of the eyebolt L.

On the segment I is formed a rib M, provided with a series of notches M adapted to be engaged by a tooth M, formed on the lever M, a rod N, provided at its front end with a longitudinal slot at, through which it is pivoted to an arm n, which is formed integral with the segment I. The lever M is pivoted to the rod N just in front of the rib M, and interposed between this point and the pivot 71 of the rod N is a coiled spring a. The rear end of the rod N is formed into a handle portion 92 The operation of this part of my machine may be described as follows: When the roller J is above the pivoted point of the lever K, the spring L reduces more or less, according to its position, the pressure of the teeth on the ground, and when the lover I is drawn all the way back it lifts the teeth several inches clear of the surface of the ground. When the roller J is on a line with the pivotal point of the lever K, the spring L has no function whatever and the carrying-frame will be free to rest on the ground by its own weight. Vhen the roller J is below the pivotal point of the lever K, the tension of the spring L exerts pressure downwardly on the lifting-lever H and the teeth-carryin g frames.

By the above-described construction the pressure required to be exerted on the teeth to accommodate different classes of soil is easily under the control of the operator, and in order to limit the depth of penetration of the teeth I have provided the rod N, which extends under the lever K and may be adjusted by means of its tooth and the rack to regulate the downward movement of the lifting-lever H and teeth-carrying frames.

The clamp B, which carries the upper end of the pivot-bar a, is made of a single piece of metal stamped into the proper shape and is adjustable laterally on the frame 0 to change the width of the machine when it is desired to operate on different widths of rows. The lower end of the pivot-bar is bent in the shape illustrated in the drawings, so as to give it strength and to bring it in closer to the wheel. A box a made in two sections, is

adapted to fit around the beginning of this curved portion and has an annular dust-cap in its lower part, adapted to receive the inner flange of the hub of the wheel; On top of this casing a and surrounding the pivotbar a is a block a and secured in recesses provided in the sides of this block a are the connecting-bars 0, which are secured at their upper ends to the clamp B, the securing-bolts passing entirely through the clamp and havingadjusting-nuts on their ends. This makes the pivot-wheel and the clamp B integral, so that by adjusting the said clamp laterally upon the frame the distance between the wheels can be regulated.

In the center of the frame 0, I arrange a I bearing-block O, which is concaved at its upper face and fits snugly around the said frame 0 and has formed on its forward side a tongue 0. Passing through the said block 0 and extending transversely-across the machine parallel with the frame 0 are the twin connecting-bars 0. A king-bolt 0 passes through the frame 0, head 0, and twin barso, said bolt being provided on its lower end with a retaining-nut. Fittingbetweenthetwinbars 0' are the foot-levers P, provided in their horizontal portions with longitudinal slots 19, through which the bolts p pass, which secures them to the twin bars 0. The lever P is bent in the form substantially as shown in Fig. 4 of the drawings and is secured at 19 to the pivot-bar a, the inwardly-extending portion 19 of the lever P forming a foot-rest and by which the pivot-wheel may be turned at the will of the operator. A bracket 10 is bolted to the arm P at a point opposite the bottom of the clamp B, which extends over said bottom for bracing and securing these parts together. Secured to the top of the upperlever o' is a U-shaped frame Q, provided with a series of apertures q, adapted to register with an aperture q, provided in the tongue 0 for the reception of a pin (1 The operation of this part of my machine will be readily understood, and itwill be seen that the machine can be quickly and easily guided by means of the operator turningthe pivot-wheel by the foot-levers, and if it should be desired to maintain the wheels at an angle to the draft of the machine, as is frequently the casein working on hillsides, the wheels can be held in such position by means of the tongue 0 and the frame Q and their registering holes and pin. The longitudinal slots 19, provided in the levers P, are for the purpose of admitting the lateral adjustment of the said levers and the pivot-wheels when it is desired to change the width of the machine.

The bearing-block a of the pivot-bar a is provided on its bottom with a smooth bearing-face which rests on the top of a similar bearing-face provided on the two-part boxing (L This boxing a bears the weightof the supporting-frame of the machine, and its smooth upper surface allows it to easilyturn The block a is provided on on the block a its front side with projecting lugs a, to which are securely bolted one end of a brace-rod E the other end of said brace-rod being secured to the front cross-bar F of the machine.

In order to securely hold the cultivatorteeth or other tool which may be employed to the carrying-frame, I have provided a clamp R,which consists of a substantially U -shaped casting having openings r in its top and bottom, one end of said opening 1 being rounded and of a diameter sufficiently large to accommodate the shank of the cultivator tooth. The width between the top and bottom of the frame R is sufficient to admit the bars G of the tooth-carrying frame. The follower R is provided on its upper and lower ends with extensions having inclined or wedge shaped faces 0*, which are adapted to engage with the inclined edges 7, provided in one end of the opening R, as most clearlyillustrated in Fig. 19 of the drawings. A screw-threaded open ing r is provided through the center of the follower R for the reception of the bolt R It will be readily seen that by adjusting the bolt R the clamp is drawn securely against the shank of the cultivator-tooth and securely binds the same .to the frame G at the same time the inclined faces r of the follower R, coming in contact with the inclined face 0", draw the upper and lower parts of the clamp R together, thereby tightly binding the same on the top and bottom of the frame G, and thereby securely holding the cultivator-tooth on its carrying-frame and also securely bind-' ing the said clamp R on the carrying-frame and preventing all possibility of displacement. This clamp also admits of both. lateral and vertical adjustment of the teeth, so that they may be easily moved to any position on the carrying-frame or adjusted to any height. the teeth to be set at any angle desired.

The position of the teeth on the carryingframes is clearly illustrated in Fig. 2 of the drawings, in which I have shown five teeth on each frame. The teeth 1 and 2 make a furrow close up to the row, and the teeth 3 and 4 cover up the furrows made by teeth 1 and 2, while the tooth 5 covers up the furrow made by the teeth 3 and 4, thus thoroughly cultivating the soil between two rows at one passage. By constructing the frame in the manner shown in Fig. 2 I am enabled to put The cylindrical shank also permits the teeth on the outside of the carryingwheels, thus enabling me to greatly diminish the distance between the said supportingwheels, thereby strengthening the machine and saving material in construction.

If it should be desired to use this machine as a single-row cultivator, the frames G canbe adjusted laterally to suit the width of the I row and the outside teeth 1 and 3 on each side of the machine be dispensed with. The inside teeth 2, 4E, and 5 could be readjusted on the carrying-frame and a fourth tooth 6 inserted on the end of said frame, as illustrated in Fig. 22 of the drawings. This would make eight teeth for cutting one row and ten for two rows, although a lesser number could be used.

In Fig. 16 I have illustrated an improved form of tool-holder, in which S designates the main shank, provided with an extension .9 on its lower end. This part is formed of a continuous piece of sheet metal stamped into the desired shape. The apertures s and 3 may be either drilled in the portions or else they could be stamped in the blank while it is being formed. The U-shaped plate S is provided with openings S S in its upper end and opening S in its lower end and is so cured to the shank s by means of a bolt passing through the lower opening S and openings s of said shank s and a bolt passing through one of the upper openings S S and opening 5 of shank s. The two holes S S are for the purpose of allowing adjustment of the plate S to change the angle of the tooth, which may be readily effected by simply removing the upper bolt and adjusting the plate S until its other opening S registers with s, the lower bolt 5 acting as a pivot. The tooth T is secured to the plate S by means of the bolt .9 An additional bolt-opening s is provided slightly below s for the purpose of readjusting the length of the tooth T after it has worn down and restoring it to the proper angle. Heretofore the shanks for the tools have been cast in a solid piece, making them heavy and expensive. By my improved manner of construction I have greatly decreased the cost of manufacture and produced a shank which is light, strong, and durable.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
